Liquid Cooling Solutions: Innovative and High-Performance Systems and Components

Electronic devices are ever more powerful, and society is increasingly more connected with continual improvements in latency driving further compute and smart device functionality adoption into new and different applications. Liquid cooling systems are now prevalent across most advanced performance industries as the most compact, sustainable, and efficient method to cool high density heat loads to enable this continual increase in power density. These systems leverage the higher heat capacity of liquid, which absorbs and transports heat at a high rate very efficiently as compared to air cooling or solid conduction. Advanced cooling systems transfer and dissipate extreme heat at a high rate, enabling high compute performance and power density levels that cannot be solved by traditional air-cooled systems.

High Reliability for Peak Performance with Sustainability in Mind

Boyd’s high reliability liquid cooling is applied at the system, enclosure, device, and component level with direct liquid cooling (DLC). Our solutions range from complex liquid cooled server systems that integrate multiple technologies to cool the largest, most demanding hyperscale compute cloud data centers in the world to compact cold plates that bring cooling directly to the silicon or power heat source with direct liquid cooling.

Increase performance efficiency, optimize energy use, maximize energy recovery, and increase reliability across all thermal system levels to minimize or remove waste, maintenance costs and downtime for a sustainable, lower total cost of cooling system ownership.

For those worried about introducing liquid into advanced electronic systems, Boyd’s liquid cooling systems have been installed in the market for decades with 20+ years of reliability data that drives continuous improvement in system design and test procedures. We offer 100% in-line thermal testing for high reliability, worry-free, leak-free liquid solutions.

Liquid Assisted Air Cooling 566x300 1

Liquid Assisted Air Cooling (LAAC)

In some systems, a liquid cooling loop cannot be utilized directly and requires the loop exchanges the heat directly to the air stream. In these cases, the Liquid Assisted Air Cooling (LAAC) is used to remove high amounts of power from the chips while rejecting the heat immediately into the air stream. This liquid assisted cooling offers customers the ability to cool the latest chips available in the market.

Liquid System Components

Liquid Cooling Components are a part of a complete liquid cooling system. Liquid cold plates and liquid cooled chassis absorb heat into a liquid cooling system as the primary direct liquid cooling interface between the liquid system and heat sources, while heat exchangers and radiators reject heat into ambient air or a secondary liquid cooling loop. These components determine how much heat a liquid cooling system can absorb or reject as the first and last processes in a liquid cooling cycle. Direct liquid cooling interface and heat rejection significantly impacts system effectiveness, efficiency, and performance, so they require significant design consideration.

Liquid Heat Exchangers

Heat exchangers (HeX) transfer heat out a liquid cooled system, either to another liquid cooling system (Liquid to Liquid) or to an air-cooled system (Liquid to Air). Liquid heat exchangers improve complete liquid cooling system efficiency by providing high surface areas for liquid paths to reject or absorb heat.

Liquid Cooling Loops

Liquid cooling loops combine direct liquid cooling cold plates with fittings and tubes to connect to pumped liquid systems to cool high-power electronics. Terminate loops with quick disconnect (QD) fluid couplings for full hot swap ability between electrical modules to maximize service efficiency.
